Archibald Turner's patent of 1941 is shown below. The curve of the fingers is formed by the longitudinal seams of the finger stalls
the following picture depicts this invention
The curve was created by joining 2 convex edges along the length of the finger stall to curve it inward toward the pocket The invention was called the Wilson "Streamline Kurv-Form". O'hara sued claiming Wilson's design not patentable. O'hara claimed the medial and longitudinal seam of the Wilson glove was commonplace practice among glovemakers. O'hara produced as evidence an old battered Ken-Wel "Dazzy Vance" model glove, showing the natural curve of the fingers to the judges and the Bert Kennedy patent of 1922 of centered finger seams.

- Dazzy Vance model

- 1922 Ken-Wel patent
Ohara won his suit against Wilson and Wilson appealed the ruling. The judges ruled the Wilson design an improvement but because of historical precedent it was declared not a patentable invention. The other glove manufactures were free to continue their own version of the curved finger glove despite Wilson's attempt to monopolize the design. A curved back glove is shown below in this 1939 OK catalog

- Ok model 740 circa 1940
This OK Mfg. glove featured the "Multiple Seamed Natural Curved Back".
